Schism

"North Africa and Rome agreed to differ on the issue of baptism, the North Africans saying that valid baptism could only take place within the Christian community which is the Church, the Romans saying that the sacrament belonged to Christ, not to the Church, and that therefore it was valid whoever performed it if it was done in the right form and with the right intentions."

Anyone who claims that their church has been doing things the same way since the crucifixion is delusional.  People were fighting over how to do things from the very beginning.
